Usage

Add the following to your Cargo.toml file:

openai_api_rust = "0.1.8"

Export your API key into the environment variables

export OPENAI_API_KEY=<your_api_key>

Then use the crate in your Rust code:

use openai_api_rust::*;
use openai_api_rust::chat::*;
use openai_api_rust::completions::*;

fn main() {
    // Load API key from environment OPENAI_API_KEY.
    // You can also hadcode through `Auth::new(<your_api_key>)`, but it is not recommended.
    let auth = Auth::from_env().unwrap();
    let openai = OpenAI::new(auth, "https://api.openai.com/v1/");
    let body = ChatBody {
        model: "gpt-3.5-turbo".to_string(),
        max_tokens: Some(7),
        temperature: Some(0_f32),
        top_p: Some(0_f32),
        n: Some(2),
        stream: Some(false),
        stop: None,
        presence_penalty: None,
        frequency_penalty: None,
        logit_bias: None,
        user: None,
        messages: vec![Message { role: Role::User, content: "Hello!".to_string() }],
    };
    let rs = openai.chat_completion_create(&body);
    let choice = rs.unwrap().choices;
    let message = &choice[0].message.as_ref().unwrap();
    assert!(message.content.contains("Hello"));
}

Use proxy

Load proxy from env

let openai = OpenAI::new(auth, "https://api.openai.com/v1/")
        .use_env_proxy();

Set the proxy manually

let openai = OpenAI::new(auth, "https://api.openai.com/v1/")
        .set_proxy("http://127.0.0.1:1080");

  • EmbeddingData's field are private?

    EmbeddingData's field are private?

    Hi there this crate is simple and great! I'm just wondering why EmbeddingData's fields are private here:

    #[derive(Debug, Serialize, Deserialize)]
    pub struct EmbeddingData {
    	object: Option<String>,
    	embedding: Option<Vec<f64>>,
    	index: i32,
    }
    

    I would like to get the embedding vector directly. PS: The link to the repo on the crate https://crates.io/crates/openai_api_rust is showing a 404, I think the link is different https://github.com/openai-rs/openapi-api
